Frequently Asked Questions
Q: Why PTFE for semiconductor applications?
A: PTFE is chemically inert to virtually all process chemicals used in semiconductor manufacturing (HF, HCl, H2SO4, solvents) and maintains dimensional stability across extreme temperature ranges. It also has ultra-low particle generation.
Q: What is the temperature range of PTFE?
A: Virgin PTFE operates from -200°C to +260°C continuously. Special filled PTFE grades (glass fiber, carbon, graphite) can operate up to 300°C intermittently.
Q: Can you machine PTFE to tight tolerances?
A: Yes, despite PTFE's high thermal expansion coefficient, we achieve ±0.03mm tolerance using temperature-controlled machining environments and compensation factors.
